摘要:
对20 a生的油松人工林和40 a生的白桦天然次生林进行生态功能的比较研究。结果表明：与白桦林相比，油松林对林内小气候的调控能力更强，但对土壤温度的调控能力低于白桦林；白桦林土壤的非毛管孔隙度高于油松林，且白桦林枯落物分解速度快，所以孔隙、养分条件优于油松林；白桦林单位枯落物的最大持水量高于油松林，但油松林枯落物含量高，所以油松林枯落物持水能力高于白桦林。
Abstract:
The ecological benefits of twenty years old Pinus tabulaeformis and forty years old Betula platyphylla were analyzed.The results indicate that P.tabulaeformis plantation’s power of regulate temperature was bigger than that of B.platyphylla,but soil temperature less than B.platyphylla.The soil non-capillary porosity of B.platyphylla was high than that of P.tabulaeformis,and B.platyphylla litter decomposition speed,so porosity and nutrient conditions than P.tabulaeformis.The Betula platyphylla’s unit litter water holding capacity was larger than P.tabulaeformis,but P.tabulaeformis litter is plenty,so P.tabulaeformis water holding capacity was better than B.platyphylla.
